Description

[Detailed description of the invention] (a) Purpose of the invention [Field of industrial application] This invention relates to a drum-type washer/dryer, and particularly relates to an improvement in the vibration-proofing structure of the drum when it rotates for dewatering.

[Prior art]

In the case of a drum-type washer/dryer, the drum rotates at high speed during dehydration. At this time, it is fine if the clothes are evenly placed in the drum, but if they are unevenly placed, very large vibrations will be generated. In order to prevent this vibration, we have devised the position and strength of the springs that suspend the aquarium, and installed vibration prevention dampers, etc., but it is not enough, and in the end, the aquarium itself is not covered with iron or concrete blocks. A so-called balance weight is installed to prevent vibration.

[Problem that the invention attempts to solve]

However, in the above-mentioned conventional products, the balance weight is extremely heavy and requires a lot of effort to transport, and at the time of packaging, it is necessary to use a packaging structure that can accommodate the weight, which leads to an increase in the cost of the product.

This invention attempts to solve the above problem, and provides a lightweight drum-type washer/dryer in which a balance weight is formed in the water tank only when necessary, and the balance weight is substantially removed when unnecessary. That is.

(b) Structure of the device In this device, an auxiliary water tank is provided in the water tank as a balance weight member.The more detailed structure is that the water tank is housed within the machine frame, and a rotating drum is placed inside the water tank. In a drum-type washer/dryer, which is constructed by being pivotally supported in a substantially horizontal direction, there is an auxiliary water tank located below the water tank in the machine frame that allows water to be taken in and taken out, and a balance weight for vibration prevention. It is fixed to the aquarium as a water tank, and is also incorporated into a part of the circulation path for cleaning water that communicates with the aquarium. This is a drum-type washer/dryer that is characterized by a built-in machine.

〔Example〕

Examples of this invention will be described below in detail with reference to the drawings, but this invention is not limited to the following examples.

FIGS. 1 and 2 each show the overall structure of a drum-type washer/dryer, in which a water tank 2 is housed within a machine frame 1, and a rotating drum 3 is further provided within the water tank 2. The upper part of the water tank 2 is suspended by a spring 4, and the lower part is supported by a damper 6 via an auxiliary water tank 5, which will be described later. A shaft body 7 is located in this water tank 2 so as to protrude from the rear to the front.
This shaft body 7 receives power from a driving electric motor 8 through a power transmission mechanism such as a belt 9, and rotates the rotary drum 3 as well as the stirring blade 10 inside the rotary drum 3. 1
Reference numeral 1 designates an opening for taking clothes into and out of the rotating drum 3.

An auxiliary water tank (storage tank) 5 is provided below the water tank 2 and is fixed to the water tank 2 with a support arm 12. The auxiliary water tank 5 is a flat-shaped housing made of a metal plate, and various pipes are connected thereto, that is, it is built into a circulation flow path for cleaning liquid that communicates with the water tank 2 . First, a pipe 13 from the rear lower part of the water tank 2 reaches the upper surface of the auxiliary water tank 5 via a plunger type valve 14, and from the rear lower part of the auxiliary water tank 5, a pipe 16 with a lint filter 15 disposed in the middle is connected. extends, pump 1
It has reached 7. Pipe 1 from this pump 17
8 is divided into two sides, and each of the two divided pipes 19 and 20 is provided with a solenoid valve 21 and 22, respectively. The cleaning liquid is sprayed into the rotating drum 3 of the water tank 2 by the operation of the pump 17. Furthermore, a pipe 23 is connected to the auxiliary water tank 5, and this pipe 23
is for water supply during the drying process, and extends from the solenoid valve 24 of the water supply flow path.

In addition to the various pipes mentioned above, a dry air pipe is connected to the auxiliary water tank 5. A pipe 25 extends from the front upper part of the auxiliary water tank 5, and this pipe 25 reaches the rear part of the water tank 2 and is connected to a heater 26 section.
A blower 28 is provided in a pipe 27 extending upward from the vicinity of the opening 11 of the water tank 2, and the pipe 27 is connected to the upper center of the auxiliary water tank 5.

This drum-type washer/dryer performs predetermined operations based on signals from a control unit, and generally performs cleaning with a cleaning liquid, rinsing with rinsing water, and drying with drying air in sequence.

During cleaning and rinsing, cleaning liquid and rinsing water are injected into the rotating drum 3 from the end of the pipe 19, reach the bottom of the water tank 2, and then reach the auxiliary water tank 5 through the pipe 13. It passes through the pipe 18 and the pipe 19 and reaches the inside of the water tank 2 again. Dehydration is performed in the final stage of the rinsing process, but this is done with the rinsing water stored in the auxiliary water tank 5. When the rinsing water is stored in the auxiliary water tank 5 in this way, since the auxiliary water tank 5 is fixed at a lower position of the water tank 2, the center of gravity of the water tank 2 is located substantially lower, and the center of gravity of the water tank 2 is temporarily lowered. To prevent vibration of a water tank 2 caused by high-speed rotation of a rotary drum 3 even if the clothes are not uniform.
Of course, some vibration occurs, but it is absorbed by the spring 4 and further damper 6. The auxiliary water tank 5 is used as a balance weight for the water tank 2 when rinsing water is stored therein.

During drying, drying air is generated by the operation of the blower 28, and this air reaches the auxiliary water tank 5 through the pipe 27. There is a pipe 23 in the auxiliary water tank 5.
Water is stored through the pipe 25, air containing dry moisture is passed through the water, the moisture is absorbed by the water, and the dry air is returned to the water tank 2 through the pipe 25. That is, the auxiliary water tank 5 also has a function as a dehumidifying cooler in the drying process.

Although the above-described embodiments are of a type in which cleaning and rinsing are performed while circulating the liquid and water, it is of course possible to perform cleaning and rinsing operations while the liquid and water are kept in the water tank. Of course, in that case, the channel configuration including the auxiliary water tank will be different as appropriate. Furthermore, the auxiliary water tank can be configured completely independent of the flow path, and of course, in that case, it is also necessary to have a configuration that allows water to be taken in and out of the tank.

(c) Effects of the invention As mentioned above, the drum-type washer/dryer of this invention has a structure in which the auxiliary water tank acts as a balance weight during dehydration, and the balance weight is substantially removed during movement or transportation. . Therefore, it can be transported in a lightweight state, and the packaging structure can be simplified, making it possible to keep costs low.

Further, an auxiliary water tank is fixedly provided below the water tank. Therefore, the center of gravity of the washer/dryer is located substantially lower, and even if the clothes in the rotating drum are not in a uniform state, the vibration of the water tank due to the high speed rotation of the rotating drum during dehydration can be reduced. I can do it. If reuse of washing water is not considered, there is no need to provide a circulation means such as a circulation pump.

Furthermore, since the auxiliary tank is built into a part of the washing water circulation path that communicates with the tank, it is possible to reuse the washing water by returning the washing water in the auxiliary tank to the tank if desired. become.

In addition, an auxiliary water tank is incorporated into a part of the drying air circulation passage communicating with the water tank. Therefore, if rinsing water is stored in the auxiliary water tank, the drying air can be passed through the auxiliary water tank to dehumidify the water during drying, and there is no need to provide a separate means for dehumidification.
